Where would you look after the alternator or generator or lights to figure out what is draining the battery in a 1989 Saab if it sits overnight?

your battery may be bad If you have one that has coves pop the covers to see if their is any water in the cells if a few are dry add water. if they are all full take it to a local shop or auto parts store they will test it. make sure you turn off all electrical things like cell phone charger make sure all dores are closed if they are ajar they may drain the battery If the battery is good, then use the following. If you have a multi-meter, connect it in series with the battery to see if there is current draw. If there is, then diconnect the fuses one-at-a-time to see which circuit is drawing power. Sometimes a bad alternator/regulator can seem like a bad battery or current draw. If the alternator output voltage is high enough to shut off the warning light, but slighly low, then the battery won't charge fast enough. If you take a few short trips, the battery will get weaker everytime you start the car. If you suspect the battery, get a charger to top off the battery. Let it sit for a couple of days, then try to start it. If it is weak, then you may have a bad battery or current leak.
